Disney researchers developed LED lamp Communication Technology

As
you might imagine, Disney researchers first built-in LED lights make toys for
communication, LED built-in photodiode can detect not only the light-emitting
light.

Typically,
intelligent devices need to rely on Bluetooth or WiFi networks. The problem is,
WiFi network is not always available, and Bluetooth will drain the battery
quickly. These facts make the Disney researchers to find new ways to make
devices communicate with each other through a LED. As you might imagine, Disney
researchers first built-in LED lights make toys for communication, LED built-in
photodiode can detect not only the light-emitting light.

Disney
calls this technology as a visible light communication system, initially using
this technology include toy cars, it is close to the light source, it can start
automatically. Another example is the little girl's clothes, to activate the
built-in flashing LED lights, close to the time when the light bar, LED lights
began to flicker on the clothes.

However,
the technology has other potential uses, such as connecting to a smartphone or
tablet LED adapter, you can receive invisible LED light signal, which will
allow the store can send a notification message to the customer accesible
smartphone or tablet than the NFC Beam currently used more efficiently.
